M&A filings: mergers, tender offers and going-private deals

Merger, tender offer and going-private filings with the SEC that name a US-listed company we cover, newest first. The list is read each business day from EDGAR's daily filing index, and every row links to the filing on EDGAR, where the full document lives.

What This Page Shows

Each row is one filing: the date EDGAR accepted it, what kind of deal filing it is, its form type, and every company the filing names, with our tickers linked to their asset pages. A filing names more than one company when its header lists a subject company beside the filer; a 425 communication about a pending merger is listed under both parties. An S-4 registration is listed under the acquirer only, so the target it registers shares for is added from a deal feed that names it.

The Filings

• S-4 and F-4: registration of the shares an acquirer issues to the target's holders in a stock or part-stock deal (F-4 when the acquirer is a foreign private issuer).
• 425: communications about a business combination, filed by either side from the announcement until the vote.
• PREM14A and DEFM14A (and PREM14C, DEFM14C): the preliminary and definitive proxy or information statement for the shareholder vote on a merger.
• SC TO-T and SC 14D9: a third-party tender offer for a company's shares, and the target board's response to it.
• SC 13E3: a going-private transaction by the company or its affiliates.

How Pending Deals Show Up in Options

Once a cash deal is announced, the target's stock usually trades just below the offer price and its implied volatility falls sharply: the price is anchored to the deal value, and most of what is left is the risk that the deal breaks. In a stock deal the target trades with the acquirer through the exchange ratio, so its options take on much of the acquirer's volatility. When a deal closes, listed options on the target are adjusted by the Options Clearing Corporation: a cash deal turns them into a claim on the cash, and a stock deal changes the deliverable into the acquirer's shares.

Shelf registrations (S-3, F-3) and securities offerings (424B prospectuses) are not listed here; they show as flags on each company's overview and SEC filings tab, linked to the filing, since a shelf or a prospectus can register debt as well as stock.
